T ol all 'who-m it may concern.' I Be it known that I, WILLIAM E. TnnAsHsn,

l a citizen of the United States, residing at Bisbee, in the county of Cochise and State of-Arizona, have invented new vand useful Improvements in Drills,'of which thefollowing is a specification.

This .invention relates to drills, riveting machines and the like. and it has forits object to produce aV machine of this class which shall be operated directly by a. gasolene or other internal combustion engine to take the place of pneumatic drills and riv-v eters such as are now ordinarily'employed. A further object of theV Invention 1s to produce 'a ,drilling and rivetlnnr machine 'which may be manufactured and operated at a comparatively moderate expense and which may be efliciently utilized above ground and under ground in places-wl1ere the supply and circulation of air is suflicient to warrant its use.

A. still further object of the-invention is to produce a drilling and riveting machine which shall be complete in itself and which may be operated without the installation of air compressors and allied machinery.

71th these and other ends in view which will readily appear as the nature of the in In the drawings-Figin'e l is a-side ele! ration, partly in section, of a machine constructed in accordance with the invention. Fig..3 is a top plan View of the same with parts broken away to expose the interior construction. "l `ig. l' is a transverse sec- -tional detail. view taken on the line fl-3 in Fig. l. Fig. 4 is a transverse sectional vic-w taken on the line 'l---4 in Fig. 2.

Corresponding parts in the'sereral figures are denoted by like characters of reference. suitably i:onstrllcted t'ranu: is prorilhal with downwardly extending braces l supporting a guide s which slidably cngages a base member 3 carrying a feed screw 4 whereby the frame may be adjusted longitudinally of the base member. The latter is mounted by a ball -and socket joint or other suitable universal joint 54 upon a foldable support which may beprovided 'with three or four le s' 6 to enable the device to be suitably a justed and leveledl 'lhe frame A carries at one end thereof a suitably constructed motor, conventionally indicated at B, said motor being an aircooled gasolene engine or other internal combustion engine of any suitable and approved construction. The opposite -end of the frame carries a. slide'- C 'constituting a hammer. The frame A is provided inter- .mediate the engine` B and the slide C with a transverse sha-ft D .having crank disks. 7 and 8 with oppositely disposed wrist pins or cranks 7 and 8, the former of which is connected bv a pitman 9 with the engine Apiston 10, while the wrist pin or crank Sis connected by a pitman 11 with the slide C that constitutes the hammer. The shaft D may also be provided with fly wheels 12 of suitable size and weight, said fly wheels being, however, made as compactly as possible to occupy as little space as possible. By making the crank disks 7 and 8 sufficiently heavy and using a center disk E, the fly wheels may probably be entirely. dispensed with.

The end of the frame adjacent to the slide constituting the. 'hammer C carries a cylindrical sleeve S which is suitably supported l for rotation and which is equipped with a handle 13 whereby it may be oscillated about ,its axis. ,The sleeve S carries a longitudi nally movable stem 14 provided at its outer end with a tool holding chuck 15. The stein 14 is forced inwardly in the direction of the hammer C by the action of a suitably arranged spring 16. A cam member 17 is pivoted upon the frame or casing A, said cam member being provided with a handle 1S, whereby it may be manipulated to place said cam member in engagement with the chuck 15 for thc purposeof holding the stem 14 projected against the tension of the spring 15, thereby retaining the stem out of range or engagement with the hammer when it shall be desired to temporarily suspend the operation of the drill or other tool carried by the chuck associated with the stem. 'lhc portion of the stem engagiugthe sleeve S is non-circular; thus, when the sleeve is rocked or o llated by handle 13, the tool carriedo5 the stenti-will be correspondinfrlyturned or'rockfurin4 the bore formed therehyf It is. obvious that shown in dottedlines in Fig. '1, vthe sleeve with the tool carrying'stem majbe cornpletely rotated.

Lubricating devices19 are to be provided' Wherever needed for the' purpose of lubrif eating the parts of the device which are subject to friction. Thel carbureter and the sparking device of the engine are to be ar' ranged in such a manner as to permit the engine to betilted to various positions during theoperation,but the .detailed construction and arrangement of these parts is not herein shown or claimed.

tion that I have provided an organized ma.- chine lncludlng a motor and a tool, such e a drill or a riveting tool associated ther with'the whole being supported in such af' mannerasto enable the tool to be'utilized K when the cam membery 17 is -movedoutl bf the path of the handle 13, as

under *conditions and substantially in lthe same manner as drills and riveters operated pneumatically, as is now-customary.

Having thus described the invention, what is claimedy as new, is-z`- In a;.device.of.the character described, a frame, an internal combustion motorl 'at one end of the frame, amo'vably supported hammer adjacent to the other enden fthe frame,

a sleeve supported for rotatie about its axis at the' end of thefralne adjacent to the hammer, a spring actuatedltool carrying stem associated with the Asleeve and lying.

1n the path of the hammer, a cam member associated with the `frame' to engage the stern to retain lthe latter in projected position, and means fortransqiitting motion from the motor to the hamner. It will he seen from the foregoingdescrip-` i 'In testimony whereof I affix my signature in presence of two Witnesses. WILLIAM E. THRASl-IER. Witnesses: y
